BICYCLE STAND Filed April 19 1933 Patented Dec. 11, 1934 7 9 Claims.

This invention relates to a stand for maintaining a bicycle in an upright position when the latter is not in use, and has for its object to provide, in a manner as hereinafter set forth, a

stand for the purpose referred to connected to and forming a permanent part of the bicycle and so constructed and arranged to enable it to beexpeditiously adjusted to and from supporting position when occasion requires.

A furtherobject of the invention is to provide, in a manner as hereinafter set forth, a stand for the purpose referred to connected to the bicycle frame at a point to prevent the operation of the latter unless thestand is in non-supporting position.

A further object of the invention is to provide, in a manner as hereinafter set forth, a stand for the purpose referred which is positioned in close proximity to the hanger box of the bicycle and when arranged in supporting position is disposed in :the path of one of the cranks of the machine, whereby if the rider attempts to start off without shifting the'stand to non-supportingposition the crank will strike the stand-and indicate to the driver thatthe stand is in supporting position.

Further objects of the invention are to provide, in a manner, as hereinafter set forth, a

stand for the purpose referred to which is simple in its construction and arrangement, strong, durable, extendible, compact when in non-extended position, readily secured to the frame of the bicycle, thoroughly efficient in its use, expeditiously ,and conveniently adjusted or extended to and from active position, and comparatively inexpensive to manufacture.

To the above ends essentially and to others which may hereinafter appear the invention consists of such parts, and such combination of tion as claimed.

In the drawing: 7 Figure 1 is a fragmentary view in side elevation of a bicycle showing the adaptation therewith of the stand in supporting position. V

Figure 2 is a fragmentary view in transverse section of a bicycle showing the stand attached therewith and in rear elevation.

Figure 3 is a section on line 3-3 Figure 1. Figure 4 is a fragmentary view in longitudinal section of the stand in non-extended position.

Figure 5 is a section on line 5-5 Figure 1. Figure -6 is a section on line 6--6, Figure 3. The stand includes a clamping. member 1,-a

' stationary combined clamping, retaining and hanger element 2, a shiftable, pivotally mounted support 3, a spring controlled couplingdevice 4 between element 2 and support 3, and connecting means 5 between member 1 and element 2.

The member 1 is in the form of a rectangular plate 5' having curved downturned end portions 6 and an opening 7 intersected by its longitudinal median and positioned adjacent to one side of its transverse median.

The element 2 includes a rectangular head piece 8 having curved upturned end portions 9 and an oval shaped slot 10 intersected by its longitudinal median and position adjacent to one side of its.

transverse median. The slot 10 'is offset with respect to opening 7. The element 2 further includes arf arm 11 depending from and disposed at an outward inclination from its top to its bottom with respect to the lower face of head piece 8; The upper end of arm 11 is flared, as at 12 and merges into the lower face of head piece 8 at the transverse median of the latter. The inner side face 14 of the flared portion 12, centrally thereof; is vertically grooved as at 15 to form a continuation of the wall of slot 10v at one end of the latter. The lower portion 16 of arm 11 is of greater width than the upper portion thereof. The outer side face 17 of arm 11 is formed with a lengthwise extending cam surface 18, a socket 19 and a stop 20. The socket 19 is arranged at the lower end of the cam surface 18 and the stop 20 below and in close proximity to the socket two having a substantially straight upper terminal portion 25 provided with an opening 26 and a rounded latching lug 2'7 spaced from the latter.

.The lug 2'7 is formed on theinner face of portion 25 in proximity to its free end.

The spring controlled coupling device comprises a headed bolt 28 which passes through slot 21 and opening 26. The head 29 of bolt 28 bears against the outer face of portion 25. Mounted on bolt 28, and interposed between arm 11 and an adjustable nut 30, on bolt 28, is a coiled spring 31 for main taining theinner side face of portion 25 against the outer side face of arm 11. The support 3 is pivoted upon arm 11 by bolt 28, and is shiftable from and to supporting section against the pulling action of spring 31.

When support 3 is in supporting position the lug 27 engages in opening 21. When it is shifted from supporting position terminal portion 25 rides upwardly on cam surface 18 untilthe lug 2'! engages in socket 19. The shifting movement of the support from its active position is arrested by stop 20. When lug 27 engages in opening 21 the spring coacts with the latter and the lug to latch support 3 in active position. When lug 27 engages in lug to latchsupport 3 in inactive position.

The connecting means 5 acts to maintain in clamping position the plate 5' and head piece 8 with respect to the braces 32 which are arranged between the hanger box 33 and the rear fork, not shown of the bicycle frame 33'. The connecting means includes a headed bolt 34 and a nut 35. a The head 36 of bolt 34 is cut away at one side as at 37 to provide a flattened surface. The bolt is disposed at an inclination with respect to plate 5' and head piece 8 and is extended through opening 7 and slot 10. The flattened surface is arranged in groove 15 whereby the shank of the bolt can seat against an end wall of slot 10. The head 36 abuts the lower face of head piece 8. The nut 35 bears against the upper face of plate 5'. The downturned end portions 6 and upturned end portions 9 bind against the braces 32.

As the upper end of the arm 11 is formed integral with and extends laterally from each side of the transverse median of head piece 8, provision should be had to prevent the weakening of the arm at its upperportion to any great extent when providing a clearance for the head of bolt 36, for

two reasons, one to prevent the arm from snapping oif when abutting an obstruction, and the other because said end receives the thrust of the weight of the bicycle when the stand is in supporting position. If the head piece 8 had its slot 10 extending an equal distance from each side of its transverse median and the member 1 had its opening 7 disposed in a like manner, then the upper portion of arm 11 would have to be grooved to an extent to weaken such end because the opening, slot and groove would then be arranged in concentric alignment, but by arranging the opening, slot and groove in the manner as shown and described, the upper end-of arni 11 is so formed to overcome the objection'referred to, and it follows by the arrangement shown and described, that the connecting means 5 must be disposed at an inclination with respect to member 1 and head piece 8 for clamping them together and also to provide for the bolt 36 to extend between and clear the brace members 32.

When the support 3 is shifted to active position it is disposed at an inclination with respect to the frame 33', and arranged in the path of the pedal carried by the crank arm 39, so if the rider does not move the support 3 to inactive position the serial will strike it. The cam surface 18 forces the-terminal portion 25 away from the non-cammed portion of the arm 11 to increase the tension of spring 26 whereby when the lug engages in the socket the support 3 will be held from accidental displacement when latched. The spring 31 further functions to prevent the accidental displacement of support 3 when the latter is latched in its active position.

The member 1, element 2 and support 3 will be formed from light metallic material, preferably aluminum.

What I claim is:

1. In a bicycle stand, an apertured clamping member for seating upon a portion of the frame of the bicycle, an apertured head piece for positioning against the lower face of said portion and including an outwardly depending means for selectively latching a shiftable support therewith in'shifted and non-shifted positions, said means having its upper end disposed at the transverse median of the lower face of the head piece and flaied outwardly and inwardly, the aperture in said head piece being offset with respect to'the socket 19, the spring coacts with the latter and.
